This title is the first of two volumes examining the artillery equipment of the British forces during the Revolutionary and Napoleonic Wars, along with Wellington's campaigns in India. Throughout this period the British Army used both Foot and Horse artillery, principally using either the 9-pounder gun or the 5.5 inch field howitzer in the field. Also covered are the smaller field guns in the 3- and 6-pounder categories and the largest, the 12-pounder field gun. This title covers the design and development of the guns, the organisation of the troops and their operational histories.
